Technical Field

[0001] This utility model belongs to the field of LED lighting technology, and specifically relates to an energy-saving LED lighting fixture. Background Technology

[0002] Currently, combined patterned lighting fixtures are widely used in people's lives. With the improvement of living standards and the increased domestic and international openness, people's demands are becoming higher and higher, and their tastes are becoming more diversified. Lighting fixture manufacturing has evolved from incandescent lamps to various light source configurations such as tungsten-sodium lamps, with a wide variety of types and functions, shifting from practicality to decoration and environmental harmony. Lighting fixture manufacturing faces unprecedented challenges. How to achieve greater energy efficiency and environmental friendliness is the key to seizing business opportunities. LED lights will be the only choice for the lighting fixture manufacturing industry. The application of LED lighting will bring about a revolution in light source usage, and its development will lead to a flourishing and competitive lighting market.

[0003] Existing LED lights often have an optical film layer added to the surface of the light source during illumination. However, the film layer is easy to peel off after long-term use, resulting in a large annual light decay rate and significant light loss, which wastes resources. Summary of the Invention

[0004] This utility model provides an energy-saving LED lamp, which aims to solve the problem that existing LED lamps often add an optical film layer to the surface of the light source during illumination, but the film layer is easy to peel off after long-term use, resulting in a large annual light decay rate and significant light loss, thus wasting resources.

[0005] This utility model provides an energy-saving LED lamp, including a housing, a threaded interface on the top of the housing, a metal reflector inside the housing, a light source holder inside the housing, an LED light source on the lower side of the light source holder, a light channel gap on the lower side of the housing, and a prism refractor threaded to the bottom of the housing.

[0006] Furthermore, the metal reflector is parabolic in shape, and the LED light source is located at the focal point of the metal reflector.

[0007] By adopting the above technical solution, the parabolic surface of the metal reflector can convert the side-scattered light of the LED light source into a beam of light that is parallel to the central axis of the lamp and perpendicular to the ground.

[0008] Furthermore, the optical channel gap is an annular cavity filled with a light-transmitting sealing gas.

[0009] By adopting the above technical solution, a sealed cavity filled with nitrogen / inert gas forms an optical isolation layer. At the same time, a sealing gasket is provided between the periphery of the optical channel gap and the outer shell to avoid dust contamination. Meanwhile, the optical channel gap can inhibit dust accumulation and reduce the annual light transmittance attenuation rate, thus maintaining the reflectivity of the reflector.

[0010] Furthermore, a planar light-transmitting area is provided at the center of the prism refraction cover, and a prism refraction area is provided on the outer side of the planar light-transmitting area.

[0011] By adopting the above technical solution, the planar light-transmitting area can pass through the main beam without obstruction, the prism refraction area can refract the side light, and refract the side light back to the metal reflector, and then reflect it again through the metal reflector.

[0012] Furthermore, the prism refraction area is a mirror surface facing the LED light source, and the preset tilt angle of the mirror surface is 10°-20°.

[0013] By adopting the above technical solution, the prism refraction area refracts the 60°-90° escape light emitted by the LED light source to the reflector for secondary reflection at an angle of 10°-20°, thereby improving the light efficiency.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By using a metal reflector, the light from the LED light source can be reflected by the metal reflector and become light perpendicular to the ground, thus improving the light efficiency.

[0016] 2. By setting the optical channel gap, this utility model can suppress dust accumulation, reduce the annual light transmittance attenuation rate, and maintain the reflectivity of the reflector.

[0017] 3. By setting up a prism refraction cover, the main beam can pass through the planar light-transmitting area without obstruction, and the prism refraction area can refract the 60°-90° escape light emitted by the LED light source to the metal reflector for secondary reflection, thereby improving the light efficiency.

The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1-2 This utility model embodiment proposes an energy-saving LED lamp, including a housing 1. The top of the housing 1 is provided with a threaded interface, which can be threaded to the ceiling. The interior of the housing 1 is provided with a metal reflector 2 and a light source base 3. An LED light source 4 is provided on the lower side of the light source base 3. The LED light source 4 is connected to an external power source through a wire. The metal reflector 2 is parabolic in shape, and the LED light source 4 is located at the focal point of the metal reflector 2. The parabolic surface of the metal reflector 2 can convert the lateral scattered light of the LED light source 4 into a beam of light that is parallel to the central axis of the lamp and perpendicular to the ground.

[0025] Reference Figures 1-2 The lower side of the outer shell 1 is provided with a light channel gap 5. The light channel gap 5 is an annular cavity filled with light-transmitting sealing gas. The diameter of the light channel gap 5 is larger than that of the metal reflector 2. The sealed cavity filled with nitrogen / inert gas forms an optical isolation layer, allowing light to pass smoothly through the light channel gap 5 without reflection. At the same time, a sealing gasket is provided between the periphery of the light channel gap 5 and the outer shell 1 to prevent dust contamination. The light channel gap 5 can also inhibit dust accumulation and reduce the annual light transmission attenuation rate, maintaining the reflectivity of the reflector 2.

[0026] Reference Figures 1-2The bottom of the outer shell 1 is threadedly connected to a prism refractor 6. The center of the prism refractor 6 is provided with a planar light-transmitting area 61. The planar light-transmitting area 61 is provided with a light-transmitting cover, so that light can be smoothly emitted from the light-transmitting cover. The light-transmitting cover can also protect the inside of the outer shell 1. The diameter of the planar light-transmitting area 61 is larger than the diameter of the metal reflector 2, so that most of the main beam can directly illuminate the outside. The outer side of the planar light-transmitting area 61 is provided with a prism refractoring area 62. The prism refractoring area 62 is a mirror surface set towards the LED light source 4. The planar light-transmitting area 61 can pass through the main beam without obstruction. The prism refractoring area 62 can refract side light and refract the side light back to the metal reflector 2, and then reflect it again through the metal reflector 2. The preset tilt angle of the mirror surface is 10°-20°. The prism refractoring area 62 refracts the 60°-90° escape light emitted by the LED light source to the metal reflector 4 for secondary reflection at a tilt angle of 10°-20°, thereby improving the light efficiency.

[0027] The specific implementation method is as follows: When in use, after the LED light source 4 is turned on, the light can pass through the light channel gap 5 and the planar light transmission area 61 and be emitted to the ground. At the same time, the light emitted by the LED light source 4 at other angles can be reflected by the metal reflector 2 and become light perpendicular to the ground and be emitted. Other light at 60°-90° will be refracted by the mirror, reflected to the metal reflector 2, and then reflected to the ground, reducing light scattering and escape, greatly improving light efficiency and resource utilization.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
